fix: Use head/cat instead of sed for multi-line YP snippet insertion

- Rename icecast.xml.base -> icecast-base.xml for editor highlighting
- Rename icecast-yp.xml.snippet -> icecast-yp-snippet.xml for editor highlighting
- Add STATION_URL env var to Liquidsoap for YP directory station link
- Production sets STATION_URL=https://asteroid.radio
- Update docker-compose.yml to pass both ICECAST_HOSTNAME and STATION_URL
- Update environment.sh.template with STATION_URL documentation
